Certify body approved system for 60335 60335 Modification Application: Lighting for Refrigerator Requirement: System should meet 60335 24V/240W, LED power supply PSU meet 61347 and 60335-1 + 60335-2-89 MW proposal: HLG-240H-24 modify cross capacitors x 2 LED with IP67 Result: MW is applying 60335 certificates with -1 and -2-89. Customer will higher flexibility and lower cost when they use the same PSU in their different projects 60335 Modification Application: coffee machine Requirement: 24V/150W, enclosed type or open frame No load power consumption PSU meet 60335-1 MW proposal: RSP-150-24 standard unit 61558 (PD3) with design refer to 60335-1 Result: Customer prefer RS-150 for cost concern. They get confirmation from certify body that RS-150 with 2 cross capacitors is sufficient for their approval. MW modify according to customer requirement but do not guarantee 60335. 60335 FAQ 60335 Q&A Questions: Can I apply 60335 on RSP-150 series? Answer: Yes RSP-150 can apply for 60335-1 CB report and certificate. But without -2, it is not a complete LVD safety, so the CE will still base on 60950/61558 60335 Q&A Questions: Why does Mean Well apply 61558 for RSP-150 Answer: In the safety standard development, 61558 is more close to 60335. for example, 60335 refer to 61558 for the transformer, further, 61558 also has a more strict safety distance rules. A power supply with 61558 can easily meet 60335-1 requirements if the special terms on 60335 are being concerned. Which means when customer taking a 61558 PSU to the certified body, they can skip a lot of test and only focus on the difference. Save time and money. 60335 Q&A Questions: What is Mean Well plan for 60335 power supply Answer: Refer to Wen/Ted. We will create a series of non-PFC enclosed type <150W for 60335-1. LRS-150/100/… New medical open frame type will also take 60335-1 into concern. 60335 Q&A Questions: Can RS-50 (60950) apply for 60335 Answer: No it is not possible without major redesign of transformer and PCB. At least it is how Mean Well understood it. However, it is always suggested to check with customer and their testing house what is their opinion about meeting 60335-1; sometimes there is a surprise. 60335 Q&A Questions: How about the EMC for Household Electronics ? Answer: The corresponding EMC regulation is EN 55014. It is more or less similar to 55011/55022, but again with additional tests. PSU that can pass 55011/55022 has very high chance to pass 55014 also. 60335 Q&A Questions: EN 62233 what is that ? Answer: Basically, it tells you whether the EM wave of the product at your hand is harmful to you… EN 62233 : Measurement methods for electromagnetic field of household appliances and similar apparatus with regard to human exposure. Previously defined in 50366, is a standard to evaluate the influence of EM field to human. It is a must for GS mark product. The requirements are different for various applications. Final evaluation should be done at system level. 60335 Q&A Questions: Does USA also apply 60335? Answer: There is UL 60335 available but it is not popular. In general, for US market, the power supply can always apply UL1012 or UL1310. For the final application, there might be other specific UL standards for that.
